Grand Central Terminal Station 100th Anniversary, New York City, United States

The original display board was an electromechanical display that displayed times and track numbers of arriving and departing trains. It contained rows of flip panels that displayed train information. It became a New York institution, as its many displays would flap simultaneously to reflect changes in train schedules, an indicator of just how busy Grand Central was. A small example of this type of device hangs in the Museum of Modern Art as an example of outstanding industrial design.
The flap-board destination sign was replaced with high resolution mosaic LCDs modules manufactured by Solari Udine of Italy, the maker of the original flap boards for train stations and airports. Similar modules are now also used on the trains, both on the sides to display the destination, and on the interior to display the time, next station, calling points, and other passenger information.
• Subway station
The subway platforms at Grand Central are reached from the Main Concourse. Built by the Interborough Rapid Transit Company (IRT) rather than the New York Central Railroad, the subway areas of the station lack the majesty that is present throughout most of the rest of Grand Central, although they are in similar condition to its track levels. The shuttle platforms were originally an express stop on the original IRT subway, opened in 1904. Once the IRT Lexington Avenue Line was extended uptown in 1918, the original tracks were converted to shuttle use. One track remains connected to the downtown Lexington Avenue local track but the connection is not in revenue service. A fire in the 1960s destroyed much of the shuttle station, which has been rebuilt. The only signs of the fire damage are truncated steel beams visible above the platforms.
